a plurality of stacked hollow rectangular flow conduits with each conduit having a conduit inlet on a first end and a conduit
outlet on a second end, wherein the hollow rectangular flow conduits are made of a non-magnetic and non-conductive material;

a first rectangular magnet and a second rectangular magnet each having a north pole face and a south pole face opposite of
each other, wherein the first and second rectangular magnets are disposed along a longitudinal axis and on opposite sides
of the stacked rectangular flow conduits such that the north pole face of the first rectangular magnet contacts a first face
of the stacked rectangular flow conduits and the south pole face of the second rectangular magnet contacts a second face of
the stack rectangular flow conduits, and the first and the second rectangular magnets provide a magnetic field that extends
between the magnets;

a first opening and a second opening on opposite walls of the stacked rectangular flow conduits extending between the first
and second rectangular magnets;

a first chamber fluidly connected to the first opening of the stacked rectangular flow conduits;

a second chamber fluidly connected to the second opening of the stacked rectangular flow conduits;

a positive electrode connected to the first chamber; and

a negative electrode connected to the second chamber;

wherein the first and second rectangular magnets generate a magnetic field that causes cations to flow from the first opening
of the stacked rectangular flow conduits to the first chamber, and anions to flow from the second opening of the sacked rectangular
flow conduits it to the second chamber.
